Abstract
A heating furnace for e.g. a hot rolling process of any object is disclosed. The furnace has a heat-resistant conveyer device for conveying a treatment object in a high-temperature atmosphere inside the furnace. The conveyer device includes an elongate cooling chamber, a rotary-member guiding passage, an endless rotary member, a drive unit and a roller. The elongate elongate cooling chamber is disposed along a direction of conveying the object inside the furnace and allowing flow of a cooling medium inside the chamber. The rotary-member guiding passage is constructed as a gutter-like recess formed along an entire length of the elongate cooling chamber. The endless rotary member includes a plurality of receivers interconnected with each other in the form of a loop. Each receiver has an object-receiving end thereof exposed from the guiding passage and the opposite end thereof disposed inside the guiding passage and the rotary member is driven by the drive unit to convey the object. The roller is rotatable to guide movement of the endless rotary member as the rotary member receives a load of the object applied onto the endless rotary member inside the rotary-member guiding passage.
